Lift system

Those levers have to be in specific positions, and the 3 point hitch trying to raise before the hydraulics kick in.

I'm going from memory here, so someone jump in if I'm wrong. But here's the way I remember those levers working:

Start out with both levers in the middle position. Pull the left lever all the way back, and raise the 3 point hitch control lever all the way up.

If the 3 point hitch comes up, you're on the right track. If not, the rest won't help and something else is wrong.

Now take the left lever and push it to the forward position momentarilly. (It should snap back to the middle position when you release it) This should make the 3 point hitch drop some.

Return the left lever to the middle position, and use the right lever to make the loader move.
